Patch 5.4.0 (10-Sep-2013) Glyph of the Battle Healer has been redesigned. The glyph now causes Seal of Insight to no longer heal the Paladin. Instead, a nearby raid or party member will receive healing for 30% of the amount the Paladin would have received from Seal of Insight.

Patch 5.3.0 (21-May-2013): Glyph of the Battle Healer now heals a nearby injured friendly target, excluding the Paladin, for 20% of damage dealt while Seal of Insight is active, down from 30%.
